Which of the following nodes allows tenant access to a VXLAN network and intra-subnet communication...

In Huawei VXLAN architecture, different gateway types serve distinct roles in tenant communication. The Layer 2 VXLAN gateway is specifically responsible for providing tenant access to the VXLAN network and enabling intra-subnet communication .

A Layer 2 VXLAN gateway (D) connects traditional Layer 2 networks (such as VLAN-based access networks) to the VXLAN overlay. It allows tenant devices or servers to access the VXLAN fabric while maintaining Layer 2 forwarding within the same subnet (same BD/VNI). This means hosts in the same subnet can communicate directly without requiring Layer 3 routing.

In contrast, Layer 3 VXLAN gateways (B) and centralized VXLAN gateways (C) are used for inter-subnet communication , enabling routing between different VXLAN segments. The default VXLAN gateway (A) typically refers to the default gateway IP configured for hosts, which is implemented via Layer 3 gateway functionality.

Huawei CloudFabric design clearly separates Layer 2 access (tenant onboarding and intra-subnet forwarding) from Layer 3 gateway functions (inter-subnet routing) .

Therefore, the correct answer is D (Layer 2 VXLAN gateway) .
